The pair of Sportech blades is made from fiberglass, a material known for its mechanical strength and its ability to combine light weight with long-lasting durability. Available in two different stiffness levels, these blades ensure optimal thrust transmission during finning.

Choosing the most suitable stiffness allows you to adapt responsiveness and movement efficiency in the water to the specific needs of freediving and spearfishing, improving control and fluidity throughout the underwater kick cycle.

Pair of Sportech Fiberglass Blades

This pair of Sportech blades is made from fiberglass, a material known for its excellent combination of elasticity and mechanical strength. The blades are specifically designed for spearfishing and freediving, ensuring effective power transfer in the water.

They are available in two different stiffness levels, allowing you to choose according to personal preferences in terms of responsiveness and efficiency during finning. The range of stiffness options helps optimize smooth movement and comfort during dives.

Sigalsub Tsunami Carbon Blades

The Sigalsub Tsunami are carbon blades designed for freediving and spearfishing, developed to deliver a smooth, progressive, and responsive fin stroke with a good balance between thrust and comfort.

Made from T700 12K Prepreg carbon fiber, they ensure consistent elastic response and efficient thrust transfer, helping reduce leg fatigue even during extended sessions.

The 23° blade-to-foot pocket angle promotes a more natural fin stroke and improves hydrodynamics during descent and ascent.

The reduced side rails allow the blade to work more freely and progressively, increasing flexibility and sensitivity while making the most of carbon’s elastic properties.

Sigalsub Tsunami blades are available in the following stiffnesses:

• Super Soft
• Soft
• Medium

This configuration lets you choose the blade response based on your finning technique and your freediving and spearfishing needs.

Dive-R Ultra Carbon Blades for Freediving and Spearfishing

The Dive-R Blades in Ultra Carbon are an Australian-made product manufactured with rigorous construction techniques, designed to deliver quality, precision, and durability for freediving and spearfishing.

These fins are used internationally by spearfishers and freedivers with high technical standards, capable of withstanding significant mechanical stress underwater while maintaining consistently high performance over time.

Materials and Construction Technologies

The DiveR carbon blades are made with premium-grade carbon fibers combined with selected resins to ensure superior elastic rebound and efficient power transfer. The special Spread Tow weave—a “wide weave”—helps minimize energy loss, optimizing every fin stroke.

They are available in two distinct stiffness levels, Soft and Medium, to suit different finning styles and effort levels.

Compatibility and Assembly

To fully exploit the qualities of the DiveR blades, mounting them on lightweight foot pockets with short rails is recommended, such as C4 Foot Pockets or the Mares X-Wing.

Alternatively, the Imersion Foot Pockets provide excellent softness, following the movement of the fin without limiting thrust-delivery efficiency.

A dedicated blade/foot pocket assembly service is also available for an optimal, customized setup.

Innovation and Composite Materials

DiveR developed this model by combining aerospace materials and advanced composites such as carbon and copper blends, carbon and Kevlar, or carbon and Innegra fibers. These technical solutions improve mechanical strength, lightness, and finning fluidity with greatly reduced muscular effort.

The result is an extremely precise and responsive blade, capable of maintaining performance over time without any loss of effectiveness, even after prolonged use while freediving.

Customization and Durability

• Wide range of colors and designs to customize the setup according to technical and aesthetic preferences.
• Original power and stiffness retention guaranteed for over 8 years of production, with no reported structural degradation.
• Suitable for both experienced freedivers and those looking for a high-quality technical product for spearfishing.
• Assembly available on any foot pocket model upon request, to maximize compatibility and comfort.

J60 Pants - Sporasub

The Sporasub J60 Pants are freediving and spearfishing pants made from smooth-skin outer Neoprene with an inner lined layer and open-cell interior, designed to provide excellent comfort and low compression at depth. The technical Neoprene construction ensures smooth movement through the water and a high-performance fit during the most demanding sessions.

Construction and Materials

• Smooth-skin outer Neoprene for reduced hydrodynamic drag and surface protection
• Inner lined layer with open-cell interior for easy donning comfort and low compression while diving
• Available in 5 mm thickness

Reinforcements and Protected Areas

• Knee reinforcement for greater durability and protection when exiting the water and in more intensive use conditions

Loading Pad

The pants feature an oversized, padded loading pad made from tear-resistant fabric, designed to better distribute speargun pressure during loading and reduce fatigue during extended sessions.

Availability

• Available thickness: 5 mm
• Available in size M

Pit Stop Salvimar Pants in 5.5 mm Open Cell Neoprene

The Pit Stop Salvimar pants are made from 5.5 mm Q-FOAM OpenCell Open Cell Neoprene, specifically designed for the needs of freediving and spearfishing.

The outer surface is lined with super-stretch nylon, providing excellent elasticity and freedom of movement during dives. The Open Cell Neoprene promotes quick drying and better thermal management, helping achieve the ideal balance between thermal protection and comfort.

The garment is equipped with a liquid expulsion valve that allows internal water to drain effectively, improving comfort and thermal performance during freediving and spearfishing sessions.

Technical features

• 5.5 mm Q-FOAM OpenCell Open Cell Neoprene
• Super-stretch nylon outer lining
• Liquid expulsion valve to help water drain out
• Available in sizes: S, M, L, XL, XXL
